In order to reduce the occurrence of aggressive behavior of children with autism, the influencing factors on children's aggressive behavior and the products that can improve the behavior are studied. Analytic Hierarchy Process (AHP) is used to establish an evaluation matrix of the influencing factors on attack behavior, and the weights of the influencing factors are analyzed; three design schemes are carried out according to the weights of the influencing factors, and the TOPSIS method is used to establish the evaluation by scoring. The matrix, according to the obtained weight values, calculates the relative fit of the positive and negative ideal solutions and selects the most effective solution. Personal cognition, parent-child relationship, peer relationship and empathy are the main influencing factors on the aggressive behavior of children with autism. Among the three products designed according to the main influencing factors, the intelligent interactive music drum design is the optimal solution. Through the analytic hierarchy process and the approaching ideal solution sorting method, the influence of subjective factors on product design can be eliminated, the design elements of toy products for children with autism can be optimized, and the market gap of aggressive behavior intervention products for children with autism can be filled, and thus the occurrence of aggressive behavior problems in children with autism can be reduces effectively.
